Please REMOVE the filenameNB.mp4 its useless
And do ADD Timecode to the recordings
right now there only is start timecode 00:00:00:00 and the duration of the recording end timecode ex. 00:00:10:10
it just makes it useless to sync with other devices like Gopro - Dji -- Cheap chinese brands and so on..
Try see for yourself in Davinci Resolve..
